Limiting Amplifiers 0.5 GHz to 18 GHz Special Purpose Amplifiers
Limiting amplifiers operate in the saturated region of their transfer function, thereby, minimizing output power variations and providing constant output over a wide input dynamic range. They are especially effective at minimizing the harmonic content of output power under limiting conditions and reproducing pulsed input signals with high fidelity by minimizing overshoot and recovery times.

Limiting amplifiers are useful in applications, which require tightly controlled power delivered over a wide range of input drive or over wide frequency ranges or even wide temperature ranges.

Typical applications include:
• Local oscillator networks
• Microwave phase/frequency discriminators
• Protecting circuitry from overdrive damage
• Removing amplification modulation from FM signals
